Server Virtualization

Random I/O and high data access demands can be severely impacted by traditional mechanical hard drives in a virtualized host. Retrieving data and servicing enterprise applications and users have become limiting factors in overall system performance. Kingston solid-state drives (SSDs) are the ideal storage accelerator solution for virtualized workloads and contribute to a fundamental goal of virtualization by doing more with less.

Cloud Computing

As cloud-based storage becomes increasingly popular, new demands are being placed on the storage infrastructure. A tiered storage model ensures that an organization has the right data on the right tier to maximize not only cost but also performance. The fast-retrieving capabilities of SSDs enable cloud services to operate at peak efficiency for each type of data being processed.

IT Applications

Kingston s SATA 3.0 Enterprise SSDs provide users with very fast data access for a wide variety of enterprise applications. They can be used as direct attached storage replacements for hard disk drives in a server or reside in external arrays to speed up storage-bound applications.

A TEAM DEDICATED TO ELEGANCE IN EVERY DETAIL

PHILIP JOSEPH MCCABE ENTREPRENEUR

Born in 1947 in the blue collar neighborhood of Dorchester in Boston, Massachusetts, Philip Joseph McCabe was literally raised in the attic of his parents’ overcrowded one-bath home, along with his five siblings. At the age of 19, with the Vietnam War nearing its height, Phil left to join the Air Force, never to return to his native Boston.

While overseas, Phil worked in the field of intelligence, becoming a specialist in the analysis of the Russian missile space program during the Cold War. For his services, he received an honorable discharge from the Air Force after serving four years, primarily in Pakistan and Afghanistan. Upon his discharge from the Air Force, Phil was given the opportunity to join the Central Intelligence Agency. He accepted their offer, and after training at CIA headquarters, was stationed in northern Iran, directly on the border with Russia. During his next four years working overseas, Phil saved every penny he could, knowing he was not meant to be a career CIA employee. In 1972, he resigned his position with the CIA to pursue his real passion – entrepreneurship.

NAS Backup

What is NAS Backup?

NAS Backup is a simple and secure online backup solution for NAS devices or Network Attached Storage devices. It keeps a copy of your files safely online, so that if the files are ever lost or damaged you can restore them quickly and easily. TAPNET Backup is very easy to set up, and once it s configured backups of new and changed files occur automatically or on a schedule.

Backup Services

How does NAS Backup differ From Other Services?

NAS Backup acts like a normal backup but allows for network attached devices to be backed up. Some devices have built in firmware for backup services, but majority do not. Most NAS devices must be backed up through a workstation that has a mapped network drive letter. The software will recognize that it is a NAS device and place the backup in a folder identified with the workstation performing the backup. The data pipes through the local workstation and then to the online space. TAPNET has QNAP and Synology client to reside directly on NAS device simplifying the process.

Backup Process

How To Backup A NAS Device?

99% of NAS devices need to be backed up using a PC or MAC that has a mapped network drive connecting to the folders on the NAS that need to be backed up. When backing up a NAS through a mapped network drive the content of the NAS will appear on the web portal in the icon of the computer doing the backup. However, with QNAP and Synology, the devices can connect directly by installing our native backup client for those devices.

It is important that a computer is selected and the NAS backup performed ONLY from that one computer. Using multiple computers to backup 1 NAS device does NOT backup the NAS to the same backup space. They WILL be separate instances of the same data. To ensure that NAS devices with multiple Terabytes of Data are backed up quickly, select a computer that is fast and always on.
Learn more

When does NAS Backup run?

NAS Backup that is being run as a NAS device backup is controlled by the backup software that is installed on the computer running the backup. The software can be setup on a schedule or using real time scanning. With a NAS device that has many files, it is recommended to use scheduled scanning with a larger lag time between scans so as to let the scan finish before the next one is scheduled to begin.

Once the initial backup is completed and there is not a significant number of files modified regularly then scans can be scheduled more frequently to ensure backups are completed within a reasonable time of changes. When a file is found that is not current with the version online, it is added to the transfer queue. it just works in the background and constantly backs up your files as you work your files are protected all of the time.
Learn more

Location

Where can I see the files I ve backed up?

The files that you ve backed up are all available from your secure web portal. Login with your TAPNET account e-mail address and password, and click on the left menu links to drill down the folders of the device that was used to backup through you ll be able to browse your files just like you can in Windows. You can download files or folders from here with one click.

Restore

How can I restore multiple files?

Whether you want to restore your files on a new computer or are recovering from an unfortunate incident, TAPNET lets your browse your TAPNET Backup account, select any file or folder and then restore it straight to your PC, either in its original location or any location you choose.

Versions

Can I get access to previous versions of files?

Yes TAPNET Backup allows you to configure any number of revisions of any file. Using the TAPNET Cloud Backup client Restore tab initiate the restore process. Double click on the file to view it s properties you ll see a list of historical versions here and can download whichever one you want.

Deleted

Can I restore deleted items?

Yes TAPNET Cloud Backup allows you to configure a number of settings on deleted file retention periods.


What is RAID storage? Webopedia Definition #raid, #redundant #array #of #independent #disks,

RAID – redundant array of independent disks

Related Terms

Originally, the term RAID was defined as r edundant a rray of i nexpensive d isks. but now it usually refers to a r edundant a rray of i ndependent d isks. RAID storage uses multiple disks in order to provide fault tolerance, to improve overall performance, and to increase storage capacity in a system. This is in contrast with older storage devices that used only a single disk drive to store data.

RAID allows you to store the same data redundantly (in multiple paces) in a balanced way to improve overall performance. RAID disk drives are used frequently on servers but aren’t generally necessary for personal computers.

How RAID Works

With RAID technology, data can be mirrored on one or more disks in the same array, so that if one disk fails, the data is preserved. Thanks to a technique known as striping (a technique for spreading data over multiple disk drives), RAID also offers the option of reading or writing to more than one disk at the same time in order to improve performance.

In this arrangement, sequential data is broken into segments which are sent to the various disks in the array, speeding up throughput. A typical RAID array uses multiple disks that appear to be a single device so it can provide more storage capacity than a single disk.

Standard RAID Levels

RAID devices use many different architectures, called levels, depending on the desired balance between performance and fault tolerance. RAID levels describe how data is distributed across the drives. Standard RAID levels include the following:

Level 0: Striped disk array without fault tolerance

Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.

Level 1: Mirroring and duplexing

Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.

Level 2: Error-correcting coding

Not a typical implementation and rarely used, Level 2 stripes data at the bit level rather than the block level.

Level 3: Bit-interleaved parity

Provides byte-level striping with a dedicated parity disk. Level 3, which cannot service simultaneous multiple requests, also is rarely used.

Level 4: Dedicated parity drive

A commonly used implementation of RAID, Level 4 provides block-level striping (like Level 0) with a parity disk. If a data disk fails, the parity data is used to create a replacement disk. A disadvantage to Level 4 is that the parity disk can create write bottlenecks.

Level 5: Block interleaved distributed parity

Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.

Level 6: Independent data disks with double parity

Provides block-level striping with parity data distributed across all disks.

Level 10: A stripe of mirrors

Not one of the original RAID levels, multiple RAID 1 mirrors are created, and a RAID 0 stripe is created over these.

Non-Standard RAID Levels

Some devices use more than one level in a hybrid or nested arrangement, and some vendors also offer non-standard proprietary RAID levels. Examples of non-standard RAID levels include the following:

Level 0+1: A Mirror of Stripes

Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.

Level 7

A trademark of Storage Computer Corporation that adds caching to Levels 3 or 4.

RAID 1E

A RAID 1 implementation with more than two disks. Data striping is combined with mirroring each written stripe to one of the remaining disks in the array.

RAID S

Also called Parity RAID. this is EMC Corporation’s proprietary striped parity RAID system used in its Symmetrix storage systems.

RAID History and Alternative Storage Options

Before RAID devices became popular, most systems used a single drive to store data. This arrangement is sometimes referred to as a SLED (single large expensive disk). However, SLEDs have some drawbacks. First, they can create I/O bottlenecks because the data cannot be read from the disk quickly enough to keep up with the other components in a system, particularly the processor. Second, if a SLED fails, all the data is lost unless it has been recently backed up onto another disk or tape.

In 1987, three University of California, Berkeley, researchers — David Patterson, Garth A. Gibson, and Randy Katz — first defined the term RAID in a paper titled A Case for Redundant Arrays of Inexpensive Disks (RAID). They theorized that spreading data across multiple drives could improve system performance, lower costs and reduce power consumption while avoiding the potential reliability problems inherent in using inexpensive, and less reliable, disks. The paper also described the five original RAID levels.

Today, RAID technology is nearly ubiquitous among enterprise storage devices and is also found in many high-capacity consumer storage devices. However, some non-RAID storage options do exist. One alternative is JBOD (Just a Bunch of Drives). JBOD architecture utilizes multiple disks, but each disk in the device is addressed separately. JBOD provides increased storage capacity versus a single disk, but doesn’t offer the same fault tolerance and performance benefits as RAID devices.

Another RAID alternative is concatenation or spanning. This is the practice of combining multiple disk drives so that they appear to be a single drive. Spanning increases the storage capacity of a drive; however, as with JBOD, spanning does not provide reliability or speed benefits.

RAID Is Not Data Backup

RAID should not be confused with data backup. Although some RAID levels do provide redundancy, experts advise utilizing a separate storage system for backup and disaster recovery purposes.

Setting Up a RAID Array

In order to set up a RAID array, you’ll need a group of disk drives and either a software or a hardware controller. Software RAID runs directly on a server, utilizing server resources. As a result, it may cause some applications to run more slowly. Most server operating systems include some built-in RAID management capabilities.

You can also set up your own RAID array by adding a RAID controller to a server or a desktop PC. The RAID controller runs essentially the same software, but it uses its own processor instead of the system’s CPU. Some less expensive “fake RAID” controllers provide RAID management software but don’t have a separate processor.

Alternatively, you can purchase a pre-built RAID array from a storage vendor. These appliances generally include two RAID controllers and a group of disks in their own housing.

Using a RAID array is usually no different than using any other kind of primary storage. The RAID management will be handled by the hardware or software controller and is generally invisible to the end user.

RAID Technology Standards

The Storage Networking Industry Association has established the Common RAID Disk Data Format (DDF) specification. In an effort to promote interoperability among different RAID vendors, it defines how data should be distributed across the disks in a RAID device.

Another industry group called the RAID Advisory Board worked during the 1990s to promote RAID technology, but the group is no longer active.
